Abstract
The survival or clearance of the avian influenza virus (AIV) of subtype H7N2 in its chicken host was evaluated using experimentally infected specific pathogen free (SPF) chickens of different age groups. Birds of different ages were successfully infected with infectious doses ranging between 10(4.7) and 10(5.7) ELD50 per bird. In infected birds, the infective virus was undetectable usually by the third week following exposure. The infectivity or inactivation time of the H7N2 AIV in various environmental conditions was studied using chicken manure, heat, ethanol, pH, and disinfectants. The H7N2 AIV was effectively inactivated by field chicken manure in less than a week at an ambient temperature of 15-20 degrees C. At a pH 2, heating at 56 degrees C, and exposure to 70% ethanol or a specific disinfectant, the AIV infectivity was destroyed in less than 30 min.

Abstract
We report here the identification of a novel DRB4*01 allele, DRB4*010304, found in a patient waiting for a liver transplantation. The new allele was detected during a routine DNA-based HLA typing. Sequencing confirmed that the new allele is identical to DRB4*01030101 at exon 2 except for position 216 where the new allele has a T instead of a C.

Abstract
Proprietary rehabilitation has developed into a distinct professional sector with procedures, practices, and philosophy that differ from those in the public rehabilitation program. As the new millennium commences, proprietary rehabilitation will face a variety of challenges and opportunities that could affect the future of this sector of the rehabilitation profession. Among these issues are changes in occupational information upon which many proprietary rehabilitation practices are based; increased opportunities for early intervention and establishment of disability management programs within industry; adjustment to the movement to a managed health care system; and the necessity to demonstrate fiscal efficacy of rehabilitation services to workers with compensable injuries. This article discusses these issues and suggests some ways in which those involved in proprietary rehabilitation can properly position themselves to address and benefit from these challenges and opportunities.

Abstract
Thrombotic thrombocytopenic purpura (TTP) has a high mortality rate if left untreated with plasma exchange promptly. We report two cases of ticlopidine-induced TTP, which lesser dosages of ticlopidine (200-250 mg/day) were prescribed and were treated with plasma exchange (PE) plus steroids. The first case was treated successfully, but the second case did not respond to our treatment and died of a progressive disease complicated with pneumonia. In sum, we recommend careful use of ticlopidine, regardless of the dosages prescribe and regardless of how long the drug is used. Moreover, the adverse effect of ticlopidine should be closely monitored.

Abstract
A 2.91-billion base pair (bp) consensus sequence of the euchromatic portion of the human genome was generated by the whole-genome shotgun sequencing method. The 14.8-billion bp DNA sequence was generated over 9 months from 27,271,853 high-quality sequence reads (5.11-fold coverage of the genome) from both ends of plasmid clones made from the DNA of five individuals. Two assembly strategies-a whole-genome assembly and a regional chromosome assembly-were used, each combining sequence data from Celera and the publicly funded genome effort. The public data were shredded into 550-bp segments to create a 2.9-fold coverage of those genome regions that had been sequenced, without including biases inherent in the cloning and assembly procedure used by the publicly funded group. This brought the effective coverage in the assemblies to eightfold, reducing the number and size of gaps in the final assembly over what would be obtained with 5.11-fold coverage. The two assembly strategies yielded very similar results that largely agree with independent mapping data. The assemblies effectively cover the euchromatic regions of the human chromosomes. More than 90% of the genome is in scaffold assemblies of 100,000 bp or more, and 25% of the genome is in scaffolds of 10 million bp or larger. Analysis of the genome sequence revealed 26,588 protein-encoding transcripts for which there was strong corroborating evidence and an additional approximately 12,000 computationally derived genes with mouse matches or other weak supporting evidence. Although gene-dense clusters are obvious, almost half the genes are dispersed in low G+C sequence separated by large tracts of apparently noncoding sequence. Only 1.1% of the genome is spanned by exons, whereas 24% is in introns, with 75% of the genome being intergenic DNA. Duplications of segmental blocks, ranging in size up to chromosomal lengths, are abundant throughout the genome and reveal a complex evolutionary history. Comparative genomic analysis indicates vertebrate expansions of genes associated with neuronal function, with tissue-specific developmental regulation, and with the hemostasis and immune systems. DNA sequence comparisons between the consensus sequence and publicly funded genome data provided locations of 2.1 million single-nucleotide polymorphisms (SNPs). A random pair of human haploid genomes differed at a rate of 1 bp per 1250 on average, but there was marked heterogeneity in the level of polymorphism across the genome. Less than 1% of all SNPs resulted in variation in proteins, but the task of determining which SNPs have functional consequences remains an open challenge.

Abstract
OBJECTIVE Analysis of X-chromosome inactivation patterns (XCIPs) is a useful tool in the diagnosis of clonal disorders. The human androgen receptor (HUMARA) locus is especially useful for clonality study. The present study was conducted 1) to determine the heterozygosity rate for HUMARA locus in Taiwanese women, 2) to determine the frequency of excessive skewing in different cell types, and 3) to determine the utility of XCIPs in the differential diagnosis of thrombocytosis. PATIENTS AND METHODS XCIPs by HUMARA-PCR assay were performed on purified granulocytes and T cells from 73 female patients presenting with idiopathic persistent thrombocytosis (IT), 10 patients with reactive thrombocytosis (RT), and 46 bone marrow samples from female controls. XCIPs of buccal mucosa cells were also compared with those of T cells in 57 patients with IT. The percentage of clonal granulocytes was calculated after correcting for the degree of Lyonization in T cells. RESULTS The heterozygosity rate for the HUMARA gene was 89.1% in Taiwanese females. The median age of informative IT patients and controls was 59 (18-92) and 58 (19-89), respectively. Excessive skewing (allele ratio <0.33) was more frequent in granulocytes than in T cells in both controls (12/43 vs 9/43, p = 0.080) and IT patients (56/64 vs 25/64, p < 0.001). XCIPs were the same for both buccal mucosa and T cells in 43 patients but were different in 14 patients. Of the 43 informative controls, 31 had a polyclonal pattern; an ambiguous pattern was found in nine; and the remaining three, aged 71, 73, and 80, respectively, had a clonal pattern. A clonal pattern was found in 42 IT patients, a polyclonal pattern in 12, and an ambiguous pattern in 10 of the 64 IT patients. The frequency of clonal, polyclonal, and ambiguous patterns in the 40 IT patients with age < or = 65 was 55.0%, 30.0%, and 15.0%, respectively. None of the IT patients aged >65 had a polyclonal disease. IT patients aged >65 had a significantly higher frequency of clonal pattern (p = 0.030) and a significantly lower frequency of polyclonal pattern (p = 0.002) than those with age <65. Of the eight heterozygous patients with RT, one aged 80 exhibited a clonal pattern, and the remaining seven had a polyclonal pattern. CONCLUSIONS The present study on Taiwanese females showed a heterozygosity rate of 89.1% for the HUMARA gene. Our results confirmed that IT is a heterogeneous disorder in terms of clonality. Twenty-three percent of IT patients exhibited a greater than 20% difference in allele expression for buccal mucosa and T cells. Presence of a clonal XCIP in young patients with IT can serve as a positive marker for the diagnosis of clonal thrombocytosis, and elderly patients with polyclonal XCIPs are unlikely to have essential thrombocythemia.

Abstract
Very few cases of rheumatoid arthritis combined with pernicious anemia have been reported in the world literature and none in the Chinese literature. A 62-year-old female initially presented with anemia. Pernicious anemia was diagnosed by characteristic blood and bone marrow morphology. Laboratory data showed a deficiency of vitamin B12 and positive anti-gastric parietal cell antibodies. Her anemia improved after vitamin B12 therapy. Painful swelling of multiple joints developed 6 years later. The clinical presentation supported a diagnosis of rheumatoid arthritis. We report herein a rare case of rheumatoid arthritis and pernicious anemia in the same ethnic Chinese patient. We also review the literature and discuss a possible association between a non-organ-specific autoimmune disease, rheumatoid arthritis, and an organ-specific autoimmune disease, pernicious anemia.

Abstract
The cDNA for an aspartyl proteinase, termed eimepsin, was isolated from an Eimeria tenella sporulated oocyst library and the deduced amino acid sequence found to be almost identical to a previously described aspartyl proteinase from E. acervulina (97.4% amino acid identity). An E. tenella cosmid clone covering the entire eimepsin gene was cloned and characterised. Sequencing revealed that the eimepsin gene spans 2.9 kb and consists of 18 exons and 17 introns. The 5' flanking region sequence of the gene contains a putative transcriptional promoter sequence (TATAAA box) and three potential transcription initiator sites (Inr sites). Expression of eimepsin at the mRNA and protein level is developmentally regulated during oocyst sporulation. The eimepsin transcript was detected in unsporulated oocysts and increased in abundance during the early part of sporulation when the oocyst undergoes nuclear division and blast formation. Thereafter, the level of the eimepsin transcript decreases and in the excysted sporozoite, no eimepsin-specific RNA was detected. Expression of eimepsin lags behind transcript expression by some hours, and the protein accumulates in the oocyst during sporocyst and sporozoite formation.

Abstract
The genome of the flowering plant Arabidopsis thaliana has five chromosomes. Here we report the sequence of the largest, chromosome 1, in two contigs of around 14.2 and 14.6 megabases. The contigs extend from the telomeres to the centromeric borders, regions rich in transposons, retrotransposons and repetitive elements such as the 180-base-pair repeat. The chromosome represents 25% of the genome and contains about 6,850 open reading frames, 236 transfer RNAs (tRNAs) and 12 small nuclear RNAs. There are two clusters of tRNA genes at different places on the chromosome. One consists of 27 tRNA(Pro) genes and the other contains 27 tandem repeats of tRNA(Tyr)-tRNA(Tyr)-tRNA(Ser) genes. Chromosome 1 contains about 300 gene families with clustered duplications. There are also many repeat elements, representing 8% of the sequence.

Abstract
Symptomatic central nervous system (CNS) involvement in chronic lymphocytic leukemia (CLL) or its variants is rare. We report two cases of CLL with leptomeningeal involvement. Patient one was an 81-year-old male who had CLL stage C (IV) at diagnosis and developed meningeal disease 29 months later. Patient 2 was a 42-year-old male with a diagnosis of CLL stage A (II) that evolved into mixed-cell CLL/prolymphocytic leukemia (PLL) 1.5 years later, with leptomeningeal infiltration of prolymphocytes developing 26 months after initial diagnosis. Meningeal leukemia was diagnosed by cerebrospinal fluid examination, with flow cytometry showing the same immunophenotypic findings of lambda-light chain restriction as the lymphocytes in bone marrow in one patient, and with morphologic characteristics exhibiting exclusively prolymphocytes in the other patient. The CNS disease of both patients responded effectively to intrathecal chemotherapy and cranial irradiation. However, both patients died of infection, a major cause of morbidity and mortality in patients with CLL. The clinicopathologic features of these two patients indicate that, despite the rarity of CNS involvement in CLL patients, any neurologic manifestation in CLL patients should arouse suspicion of meningeal leukemia and patients should be examined and managed accordingly.

Abstract
A survey of support services for adults with development disabilities living in community settings in Canada was conducted. Information gathered on services and changes occurring in the community services landscape is discussed. Along with a diminution of government's role in funding and guiding service provision, Canada has witnessed the emergence of private-for-profit services, a relatively recent phenomenon in human services. Differences between the private-for-profit and nonprofit sectors are discussed, including a greater propensity in the nonprofit agencies to engage in advocacy and community education. Overall, evidence indicates that some services are beginning to incorporate individualized approaches to funding and support. Implications for government and for services of emergent patterns of support are noted.

Abstract
BACKGROUND Immunoglobulin D (IgD) multiple myeloma (MM) is rare, accounting for less than 2% of all patients with MM in Western countries. In Taiwan, the frequency and clinicopathologic features of IgD MM have not yet been reported. METHODS The clinicopathologic features and treatment outcome of patients with IgD MM diagnosed between January 1, 1982, and December 31, 1998, in Chang Gung Memorial Hospital were retrospectively reviewed. Nineteen patients with IgD MM were diagnosed. Of those patients, the medical records of 16 were available for review. RESULTS Most of the patients were male (11/16) with a median age of 59 years. The most common presenting features included bone pain (56%), gastrointestinal discomfort (38%), general malaise (38%), and body weight loss (25%). The majority of patients had cytopenia (88%), renal function impairment (75%), hypercalcemia (63%), hyperuricemia (69%), elevated beta 2-microglobulin levels (86%), and Bence Jones proteinuria (92%). Serum protein electrophoresis showed an M-peak in 9 cases (9/12), whereas immunoelectrophoresis or immunofixation identified an IgD monoclonal gammopathy in all 16 patients. All of the M-proteins were of a lambda-light chain type. The IgD level ranged between 584 and 129,000 IU/ml (normal, < 100 IU/ml). All the patients had stage III disease except one (stage I). Four patients were still alive at the time of this analysis. The median survival time was 12 months. Infection was the leading cause of death (50%). CONCLUSION The present series showed that IgD MM had aggressive clinical features, male predominance, a high frequency of renal function impairment, high incidence of M-protein undetected by serum protein electrophoresis, a predilection for lambda-light chains, and a short period of survival.

Abstract
There is now widespread interest in developing social policies and practices that are grounded in principles of independent living. The Independent Living (IL) paradigm reflects a shift in thinking away from traditional approaches to supporting persons with disabilities. Independent Living Centres (ILCs), which started in the early 1970s in the United States, and in the 1980s in Canada, are now a major force in the promotion of the IL concept worldwide. The guiding principles of these consumer-driven centres include: promoting an empowerment philosophy that incorporates consumer control/self-direction over decision-making; offering cross-disability support; providing options/choice and flexibility; and encouraging inclusion and full participation. Despite their prevalence, a surprisingly limited body of research exists on the impact of ILCs. A survey was used to investigate the impact of ILCs in Canada on their communities of interest (groups connected to the ILCs). Surveys were sent to formal organizations, informal groups, and family/friends. A final response rate of 52.6% was achieved (111 of 211 surveys returned). Overall, moderate to good levels of familiarity, involvement, and impact were found. The results affirmed the importance of independent living centres to individual empowerment, community change, and the IL movement.

Abstract
Chlamydia pneumoniae is emerging as a significant human pathogen. Infection causes a range of respiratory tract diseases and is associated with atherosclerosis. A vaccine could provide a considerable public health benefit; however, antigens able to elicit a protective immune response are largely unknown. A panel of open-reading frames (ORFs) from the C. pneumoniae genome sequence was screened for ability to elicit protective responses. Balb/c mice immunized with DNA containing the ORFs were tested for their ability to limit lung infection following an intranasal challenge. Immunization with DNA encoding the major outer membrane protein or an ADP/ATP translocase (Npt1(Cp)) of C. pneumoniae resulted in a reduced bacteria load in the lung after challenge. The identification of these antigens as protective is a significant step toward development of a C. pneumoniae vaccine and demonstrates the feasibility of using a DNA immunization strategy to screen the C. pneumoniae genome for other protective ORFs.

Abstract
The fly Drosophila melanogaster is one of the most intensively studied organisms in biology and serves as a model system for the investigation of many developmental and cellular processes common to higher eukaryotes, including humans. We have determined the nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map. Efforts are under way to close the remaining gaps; however, the sequence is of sufficient accuracy and contiguity to be declared substantially complete and to support an initial analysis of genome structure and preliminary gene annotation and interpretation. The genome encodes approximately 13,600 genes, somewhat fewer than the smaller Caenorhabditis elegans genome, but with comparable functional diversity.

Abstract
We used DNA fingerprinting to examine reproductive skew in cooperatively breeding white-winged choughs, Corcorax melanorhamphos, which live in groups of up to 20 individuals. Before a severe drought, groups that had been stable for multiple years were characterized by long-term monogamy involving a single breeding pair (high skew). After the drought, new groups formed from the amalgamation of multiple individuals and coalitions of relatives. At most one member of each faction succeeded in breeding, such that skew was dependent on the number of unrelated factions, and not group size. In the new groups, dominant males and females with supporting relatives were always successful. Whereas most females without support also gained breeding positions, many males without family support failed to breed. Thus subordinates gain indirect fitness by first helping related males to secure a breeding position, and then helping to raise their young. Our study demonstrates the advantage of operating in coalitions, and suggests that the acquisition of future allies may be a major benefit of helping behaviour in this species.
